Telegram is adopted widely by the “crypto community”. But Monero should not be apart of this, as it’s a centralized platform doing zero metadata protection and only encrypted on mobile.

Then avoid X, Reddit or Discord. You need to be in different channels to teach and trade with people about Monero.
